ISO 2538-2:2014(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement. For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO s adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information The committee responsible for this document is ISO/213, Dimensional and geometrical product specifications and verification. This first edition of ISO 2538 2, together with ISO 2538 1, cancels and replaces (ISO 2538:1998), which has been technically revised. ISO 2538 consists of the following parts, under the general title Geometrical product specifications (GPS) Wedges: Part 1: Series of angles and slopes Part 2: Dimensioning and tolerancing iv ISO 2014 All rights reserved
ISO 2538-2:2014(E) Introduction This part of ISO 2538 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links1, 2 and 3 of the chain of standards on angle. The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253 1 apply to specifications made in accordance with this document, unless otherwise indicated. For more detailed information on the relation of this part of ISO 2538 to other standards and to the GPS matrix model, see Annex A. In this part of ISO 2538, the figures illustrate the text only and should not be considered as design examples. For this reason, the figures are simplified and are not to scale.

INTERNATIONAL STANDARD ISO 2538-2:2014(E) Geometrical product specifications (GPS) Wedges Part 2: Dimensioning and tolerancing 1 Scope This part of ISO 2538 specifies methods for the dimensioning and tolerancing of wedges. NOTE For simplicity, only truncated wedges have been represented in this part of ISO 2538; however, this document can be applied to any type of wedge. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 2538 1:2014, Geometrical product specification (GPS) Wedges Part 1: Series of angles and slopes 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 2538 1 apply. 4 Dimensioning of wedges 4.1 Characteristics of wedges In order to define a wedge, the characteristics and dimensions shown in Table 1 may be used in those combinations most appropriate for the function of the wedge.
